Screenshots of what is purportedly Windows 10 Mobile build 10534 have been leaked to the Internet, showing off a few minor changes that imply Windows 10 could support USB tethering and file sharing over Wi-Fi in the future.

The screenshots, which were posted on the Poland-based, Windows-focused forum WiindowsMania.pl, do not show any changes at all concerning the appearance of Windows 10 Mobile. It appears build 10534 will look very much like build 10512, which is what is available as a Technical Preview to Fast Ring Insiders right now.

Digging further into the settings page, however, shows us a couple of connectivity changes for developers. Under For Developer Settings, we find an option to make devices visible for USB connections. This can mean Windows 10 Mobile might offer the option to do simple USB tethering to something more exciting, such as the ability to allow users to share files over a home Wi-Fi network.

The second option enables the device to become visible for USB EEM connections. EEM, which stands for Ethernet Emulation Model, functions as an Ethernet interface using a USB adapter and can potentially provide the ability for users to download content to their devices through the Internet if connected via USB.

WindowsMania.pl also says that build 10534 will come with the usual improvements to speed and efficiency, which is not surprising. When Microsoft released build 10512 to Fast Ring insiders, Windows Insider chief Gabe Aul emphasized that "core quality" was the focus for the mobile version of Windows 10.

"The team was very focused on our Windows 10 release for PCs and tablets, and we needed to do some prep work for Mobile to move to a new branch," Aul said in a blog post. "I expect the builds to be out more frequently again as we go forward from here. Our major focus on Windows 10 Mobile right now is on improvements to core quality."

Build 10534 is reported to experience issues with the Windows Store that causes it to crash every now and then. It is expected to be the next build that Microsoft could be planning to roll out to Fast Ring Insiders next week, although Aul had earlier tweeted that he was using Build 10532.

@sai_patro Okay :-) No new mobile builds today. We were looking at 10530 as a candidate, but want to get one key fix in before we go out.
